BROODER.

SPECIFICATION forming part of Letters Patent No. 442,007, dated December2, 1890.

Original application filed July 13, 1889, Serial No. 317,481. Divided`and this application filed June 30, 1890, Serial No. 357,301. (Nomodel.)

To @ZZ whom t may concern:

Be it known that I, GEORGE Il. BISHOP, a citizen of the United States,residing at Northport, in the county of Suffolk and State of New York,have invented certain new and useful Improvements in Broeders, of whichthe following is such a full, clear, and exact description as willenable any one skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specilication.

This application is a division of my original application, Serial No.317,481, filed July 13, 1339, for improvements in incubators.

My invention relates to improvements in brooders, or socalled artificialmothers, for rearing young fowls or chicks; and the objects of theinvention are to provide a brooder of a simple construction, wherein theair may be continually circulated and maintained at or about a uniformtemperature.

In the accompanying drawings, illustrating an embodiment of myinvention, Figure 1 is a sectional View of my improved broeder, taken ona vertical plane through the center of the apparatus; and Fig. 2 is ahorizontal sectional view of the same.

Referring to the drawings, in which like numbers of reference designatelike parts, S designates the brooding-chamber, the walls of which aredouble, with a considerable space 9 between them. y This space 9 may bepacked with a suitable non-conductor of heat, or may be left as anairspace to act as a heat-retaining jacket for the chamber to preventthe rapid radiation of heat therefrom. One side of the chamber isprovided with a door 10, through which access may be gained to any partof the interior of the chamber.

The air is introduced iut-o the upper part ot' the chamber 8 throughmeans ot' pipes 11 11, shown, preferably, as four in number, and locatedone near each corner and running from the outside of the bottom of thechamber vertically through space 9 to nearthe top, thence extendinghorizontally into the center ofthe chamber, where they open into acommon dischargepipc 12. The induction-pipe 12 is arranged vertically,and has a closed bottom and an open top or mouth, which empties almostdirectly against the upper side of the chamber. The air is led from thechamber S by means of a set of outflow-pipes 13 13, that run radiallyfrom the centrallydisposed eduction-pipe 14, provided with deflector 15,and set down through the inner wall of the chamber. The outflow-pipes 1313 are arranged within the space 9 and extend horizontally from theeduction-pipe 11- one to each corn er of the chamberthence u pwardly tothe top of the chamber and hori` zontally inwardly to the center of thetop side thereof, where they open into a tlue 1G, that is set downthrough the outer wall of the chamber, and is provided with a defiector17 for checking the outflow of the air, in order t0 produce a sluggishmovement thereof through the chamber and avoid strong drafts. The air isheated to the desired degree as it is introduced into the chamber bymeans of a hotwater tank 18, which is disposed horizontally in the upperpart of the chamber, so that the air, almost immediately upon enteringthe chamber, may be passed over the radiating-surface of the tank, andthus warmed before passing down to the lower part of the chamber to thebroeder-cage.

The tank 18 is made of a suitable metal, and is connected by thecirculating-pipes 33 3a 35 with the water-heater 19, which supplies theWater thereto, and is heated by a lamp 36, set on a bracket Li1.

No claim is here made to the hot-water tank 1S, the heater 19, and thelamp 36, though the same are my inventions.

Near the bottom of the chamber S is located the brooder-cage 52, havingthe sides and top thereof formed of suitable open-work.

'In the construction shown the cage consists in a door49,suitablyclevated and supported above the bottom of the chamber withside walls 53, made, for instance, of gauze-work. The top of this cageis covered by an openwork screen, comprising the gauze 47 set in a frame50, which is supported loosely on blocks 51. From the gauze 17 are hungthe broeder-strips 4S, which may be placed as close together asdesirable, so as to present a suitably dense mass. These strips arepref- IOO erably made of flannel, though any suitable materia-.l may beused, and are designed to `take the place of the feathers of the naturalmother hen. The broeder is so situated that the Warm air in passing fromthe heater 18 to the dischargeflue 14 will circulate freely through andabout the broeder-cage, so as to supply in a uniform manner the heatedfresh air to the chicks. If desired, evaporationpans may be used Withthe brooder vfor the purpose of moistening the air.

The discharge-pipe 12 and the inner ends of the air-pipes 11, beinglocated near the top of the chamber immediately above the heating device18, these parts will be heated to such a degree as to cause the lowerends of the pipe 11 to suck in the fresh air and empty it in the upperpart of the chamber, thereby insuring a good circulation of the air.

Havingthus described my improvements in brooders, what I claim as myinvention, and desire to secure by Letters Patent, is-.-

1. A broeder-cage consisting in the combination, with the floor 49 andthe side Walls of the cage, of a gauze top 47, the strips 48, made offabric or like material doubled upon itself and hung over the strands ofthe gauze 47, with the free ends thereof depending into the cage,substantially as and for the purpose set forth.

2. In a broeder, the combination, with a chanrberS, provided withaheating device for warming the air therein,of abrooder-cage 52,locatedtnear the bottom of the chamber and having its floor 49 elevatedabove the floor thereof, and a space between the sides of the cage andthe sides of the chamber, the said cage being provided With aperforatedor openwork top 47, having strips of fabric 4S orlike material hungtherefroimasystem of in flowai rpipes 1 l,extending from theeXterior ofthe bottom of the said chamber and vertically to near the top thereof,then horizontally inwardly to near the center of the top of the chamber,where they empty, a set of outflow-pipes 13, extending from about thecent-er of the bottom of said chamber at a point between the floor ofthe same and'the broeder-cage to the exterior' of said chamber at thetop thereof, substantially as and for the purpose set forth.

In a brooder, the combination, with a chamber S, having a heating devicefor Warnr ing the air therein, of a broeder-cage 52, located near the`bottom of the said chamber, with its door 49 elevated above the bottomthereof, and-having a space between its sides empty, the eduction-pipes14 and 16, located,`

respectively, at the bottom and top of said chamber, the one openinginto the chamber and the other opening to the exterior thereof,

a set of imiow air-pipes 13, extending around the sides of the chamberand connecting the said pipes 14 and 16, for discharging the air fromthe chamber, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand, this 19th day of June,1890, in the presence of the two subscribing witnesses.
